The Umarex HDS68/TS68 service kit contains one CO₂ compensating screw and an assortment of O-rings, springs and washers. It supplies replacement hardware for the double-barrel platform. For barrel cleaning, the separate .68 Single Swab serves a different purpose: it is a cleaning tool rather than a parts assortment.
Match the service kit to the part you need
One compensating screw is expressly listed in the package. That makes the kit’s contents straightforward to compare when this is the replacement you are looking for. The rings, springs and washers are listed as an assortment, without a separate size or quantity for each item. For a particular ring or spring, ask Z-RAM to confirm its size and whether it is included before ordering; the photo alone does not establish the exact size.
The model name matters as much as the part type. HDS68 and TS68 are the confirmed names for this double-barrel platform, and the kit specifically names that platform. A service kit for another .68 marker may use the same general words—O-rings, springs and seals—without supplying the same components. Caliber alone is therefore not the selection criterion for these internal parts.
Choose a swab for the cleaning task
The Single Swab is listed as a yellow .68 barrel cleaner with a rigid, non-folding form and a total length of 40 cm. These are the useful details when choosing a cleaning implement: its caliber, shape and size, alongside the cleaning directions for your HDS68/TS68.
The two offers below answer two different needs. The Umarex kit is the relevant offer for its stated replacement hardware; the separate Single Swab is the relevant offer for a .68 barrel-cleaning implement. Start with the task you actually have, then compare the listed contents or tool dimensions.
Choosing a cleaning tool as well as replacement parts? The .68 barrel-cleaning tool size guide explains why caliber, overall tool length and usable reach are different checks.
